Judge uses CPU time or total time?

[guptaaditya13]

I have doubt, while executing, the judge considers the total time spent by the process or the time spend by the process in CPU. ideally it should be the second one.

Yes, this is a bug that needs to be fixed. This should be the CPU time, but right now it only measures the total time spent by the process.

@sankha93 do you have any idea how we can implement it?

[ngsankha]

Yes, I think some form of the ulimit needs to be set to fix the maximum CPU time of the program.

That said, I do agree there needs to be a better sandbox implementation for this. I have some ideas for it, may be I'll get to implementing it soon.
